The product specification describes the requirements of the Cylindrical Lithium-ion Cell to be supplied to the
customer by Lishen Battery Co.,Ltd.
2 DESCRIPTION AND MODEL
2.1 Description : Cylindrical Lithium Ion Cell
2.2 Model : LR2170SC
3 GENERAL SPECIFICATIONS
3.1 Nominal Capacity 5000mAh (at 0.2C Discharge)
Nominal capacity is measured by the discharge at 0.2C to 2.75V end voltage after standard fully charged
according to specification at 25℃.
3.2 Maximum Charge Voltage 4.20V
3.3 Average working Voltage 3.65V@0.2C
3.4 Standard Charge Method Constant Current and Constant Voltage (CC/CV)
Current 0.5C (2000mA) Voltage 4.2V End Current 80mA±5mA
3.5 Maximum Charge Current 0℃ ≤ T ≤ 5℃ 0.1C (400mA)
5℃ < T ≤ 15℃ 0.2C (800mA)
15℃ < T ≤ 45℃ 0.5C (2000mA)
3.6 Standard Discharge Constant Current (CC)
Current 0.5C (2000mA) End Voltage 2.75V
